T-Mobile is ready to pull the metaphorical VoLTE lever marked Seattle, giving the city early access to the upgraded infrastructure the carrier hopes to roll out to more parts of the country over the course of the year. This voice over LTE connection will allow consumers to use voice and data at the same time, as voice calls will go out over IP on LTE rather than taking the current switched-circuit path approach.

T-Mobile has announced a software update for its version of the Galaxy S5 that, while nothing exciting, should address an issue some customers have experienced. The change log contains a single item, an improvement that alleviates occasional incoming SMS/MMS failure. Following the update, the S5 should receive messages more reliably, assuming it hasn't worked fine for you thus far. The version number is G900TUVU1ANE5.

The update is 131MB large and is available as an OTA or via Samsung Kies.

If you've got an HTC One on T-Mobile, whether it's the original from 2013 or the new One M8, you have a software update headed your way. Nether is packing a new version on Android, because they're both running KitKat, but new features are inside nonetheless. One M7 owners get a refreshed version of HTC's Sense interface, and One M8 owners now have access to the Extreme Power Saving mode.

You can't have everything, which is why the ZTE Concord II exists. This entry-level smartphone has just been announced for T-Mobile and Metro PCS. It will be on sale later today on the magenta carrier and next week on Metro PCS.

This phone isn't going to set the world on fire with its specs, but it's going to be available in carrier stores for cheap. Here's the full spec sheet.

People who bought the un-flattened LG G Flex on the un-carrier T-Mobile should be on the lookout for a chocolate dose of new features. The carrier has announced a software update is hitting devices starting today, bumping them up to Android 4.4 and software version D95920d.

Bucking the status quo of American wireless companies seems to be working for Legere and Company. For the first three months of 2014 T-Mobile added 2.4 million new wireless customers, according to the company's financial report published this morning. In the crucial post-paid segment (as opposed to the less reliable prepaid segment) T-Mobile added 1.3 million new subscribers.

While T-Mobile is still a long way away from 800-pound gorillas AT&T and Verizon Wireless, it's safe to say that the lower prices and ceaseless "Uncarrier" promotions are having an effect.

T-Mobile introduced a whirlwind of changes last year as it rebranded itself as the "Un-carrier," with perhaps its most substantial shift being the decision to forgo annual contracts, breaking away from a long-standing practice among carriers in the US. Now the company is doing away with another perpetual mobile pain in the rear by eradicating its domestic overage charges. This applies regardless of whether you're on a Simple Choice plan, the new Simple Starter, or an older plan - and it will take place starting in May, with those bills arriving in June.

Three of the big four American carriers started offering the HTC One M8 on March 25th, the day the phone was announced. One, T-Mobile, is just getting the phone today. But last does not mean least, and with this un-carrier's low prices, there's plenty of reason to have waited. Unfortunately (and unsurprisingly), the affordability does not start with the phone itself, which is now available for $26.50 a month for twenty-four months or $636 all at once.

On the off chance you were looking for another reason to be annoyed at the big US carriers, you may have found it. According to Fierce Wireless, AT&T isn't the only carrier that opted to remove Download Booster from the new Samsung Galaxy S5 – both Verizon and Sprint have yanked Samsung's LTE-WiFi merging feature. That would make T-Mobile the only US national carrier that supports it. Update: We've been tipped that the US Cellular Galaxy S5 will have Download Booster as well.

Saturday, April 12th is increasingly looking like a big day for T-Mobile. Yesterday the carrier introduced its new "Simple Starter" plan going for $40. Now, for day 2 of 3 "un-carrier" announcements leading up to this weekend, T-Mobile has unveiled "Operation Tablet Freedom." This offer entices customers to purchase LTE versions of tablets for the same price as the Wi-Fi versions. The company will then provide 1GB of free 4G LTE data for the remainder of the year in addition to the 200MB of free data lasting for the life of the device.
